Description
本發明提供一種觸摸屏及觸控顯示裝置。The invention provides a touch screen and a touch display device.
隨著平面顯示技術的蓬勃發展及製造成本的日益降低，具有輻射低、厚度小、功耗低等優點的平面顯示裝置越來越受到消費者的青睞，因此被廣泛地應用在電子產品中。為了符合現代人對於更加便利、更加直觀的人機界面的需要，近年來市場上逐漸推出各種各樣具有觸控功能的平面顯示裝置，即觸控顯示裝置。With the rapid development of flat display technology and the decreasing manufacturing cost, flat display devices with low radiation, small thickness and low power consumption are increasingly favored by consumers, and thus are widely used in electronic products. In order to meet the needs of modern people for a more convenient and more intuitive human-machine interface, various flat display devices with touch functions, namely touch display devices, have been gradually introduced in the market in recent years.
觸控顯示裝置一般可以分為外置式和內嵌式兩種；其中，外置觸控顯示裝置是在傳統的平面顯示裝置基礎上附加一觸控屏，從而將觸控功能和顯示功能集成。The touch display device can be generally divided into an external type and an in-line type; wherein, the external touch display device is attached with a touch screen based on the conventional flat display device, thereby integrating the touch function and the display function.
近年來，採用奈米碳管導電層製作的觸摸屏由於耐用性較好，已經越來越多的應用到各種電子產品中。然而，奈米碳管導電層的導電性與其內部的奈米碳管的長度相關，通常地，奈米碳管的長度越長，其構成的奈米碳管導電層沿該長度方向的導電性就越差，這一特性極大限制了奈米碳管導電層的製作尺寸。另外，受奈米碳管晶元大小的限制，奈米碳管導電層的在垂直奈米碳管延伸方向上的寬度也難於製作成較大尺寸。也就是說，目前，奈米碳管導電層難於製作成較大尺寸，因而採用奈米碳管導電層製作的觸摸屏也難於製作大尺寸觸摸屏幕，故，現有奈米碳管導電層製作的觸摸屏難於滿足人們對較大尺寸觸摸屏幕的需求。In recent years, touch screens made of conductive layers of carbon nanotubes have been increasingly used in various electronic products due to their durability. However, the conductivity of the carbon nanotube conductive layer is related to the length of the inner carbon nanotube. Generally, the longer the length of the carbon nanotube, the conductivity of the carbon nanotube conductive layer along the length. The worse, this feature greatly limits the size of the carbon nanotube conductive layer. In addition, due to the limitation of the size of the carbon nanotubes, the width of the carbon nanotube conductive layer in the direction in which the vertical carbon nanotubes extend is also difficult to make a large size. That is to say, at present, the carbon nanotube conductive layer is difficult to be made into a large size, and thus the touch screen made of the carbon nanotube conductive layer is also difficult to make a large-sized touch screen. Therefore, the existing nano carbon tube conductive layer is made of a touch screen. It is difficult to meet the demand for larger size touch screens.
鑒於以上內容，有必要提出一種較大尺寸的奈米碳管導電層製作成的觸摸屏。In view of the above, it is necessary to propose a touch screen made of a large-sized carbon nanotube conductive layer.
也有必要提供一種採用上述觸摸屏的觸控顯示裝置。It is also necessary to provide a touch display device using the above touch screen.

The screen requires, further, the carbon nanotubes of the first and second touch sub-screens have different extending directions of the carbon nanotubes, and can ensure a touch sub-screen of carbon nanotubes on another touch sub-screen The splicing in the extending direction effectively improves the problem that the carbon nanotubes of the one touch sub-screen are inferior in conductivity along the length direction thereof, thereby obtaining a touch screen having good conductivity and large size.

與先前技術相比較，本發明觸摸屏10中，將原本相互獨立製作的兩塊觸摸子屏11a、11b拼接於一體，由於每一觸摸子屏11a/11b的周邊區域的寬度較小，故基本不影響該觸摸屏10的整體使用，但通過上述拼接可以獲得較大尺寸的觸摸屏10，滿足人們對較大尺寸觸摸屏幕的需求。Compared with the prior art, in the touch screen 10 of the present invention, the two touch sub-screens 11a, 11b which are originally made independently of each other are integrated into one body. Since the width of the peripheral area of each touch sub-screen 11a/11b is small, it is basically not The overall use of the touch screen 10 is affected, but a larger size touch screen 10 can be obtained by the above stitching, satisfying the demand for a larger size touch screen.
進一步地，該第一及第二觸摸子屏11a、11b的奈米碳管導電層13的奈米碳管的延伸方向不同，可以保證一個觸摸子屏在另一個觸摸子屏的奈米碳管的延伸方向上拼接，有效改善由於該一個觸摸子屏的奈米碳管沿其長度方向的導電性較差而限制其製作尺寸的問題，得到導電性較好且尺寸較大的觸摸屏幕。Further, the carbon nanotubes of the first and second touch sub-screens 11a, 11b have different directions of extension of the carbon nanotubes, thereby ensuring a carbon nanotube of one touch sub-screen on the other touch screen The splicing in the extending direction effectively improves the problem that the carbon nanotubes of the one touch sub-screen are inferior in conductivity along the length direction thereof, thereby obtaining a touch screen having good conductivity and large size.
另外，由於該第一及第二觸摸子屏11a、11b的奈米碳管導電層13的奈米碳管的延伸方向不同，使得該第一及第二觸摸子屏11a、11b的佈線區域的位置可以錯開，具體地，該第一觸摸子屏11a的第一周邊區域111與該第二觸摸子屏11b的第四周邊區域114接觸並拼接，而該第二觸摸子屏11b的第四周邊區域114未設置該第一、第二導電線路14、16從而寬度較小，可使該第一觸摸子屏11a的觸摸區域110與該第二觸摸子屏11b的觸摸區域110之間的無效區域較小，更方便該觸摸屏10的整體使用。In addition, since the extending directions of the carbon nanotubes of the carbon nanotube conductive layer 13 of the first and second touch sub-screens 11a, 11b are different, the wiring areas of the first and second touch sub-screens 11a, 11b are The position may be staggered. Specifically, the first peripheral area 111 of the first touch sub-screen 11a is in contact with and spliced with the fourth peripheral area 114 of the second touch sub-screen 11b, and the fourth periphery of the second touch sub-screen 11b The area 114 is not provided with the first and second conductive lines 14, 16 so that the width is small, and the invalid area between the touch area 110 of the first touch sub-screen 11a and the touch area 110 of the second touch sub-screen 11b can be made. Smaller, more convenient for the overall use of the touch screen 10.
